Nanogen Receives Final Stockholder Approval on Debt Financing

(Nanowerk News) Nanogen, Inc. (Nasdaq: NGEN) announced today that it has received stockholder approval on the third of the three proposals presented at its special meeting of stockholders on February 1, 2008. During the special meeting, stockholders approved two of the proposals but insufficient votes were obtained to approve Proposal #1, in which the board of directors was seeking approval to ratify the company's debt financing of August 2007. Accordingly, the meeting was adjourned until February 11th to provide shareholders with additional time to vote on the proposal. Today the company announced it has received the necessary votes to approve this proposal.

As stated in the February 1st announcement, approval of all three proposals is an important component of the company's restructuring activities and will provide the company with increased financing flexibility until positive cash flow is achieved. The company expects to achieve cash flow breakeven in late 2008 based on its current revenue and expense projections for the year.
